' Fans, of which the following is a specification. This inventionrelates ,.to improvements in attachments for fans, and has particularapplication to a device, for deflecting the gir in desired directionsfrom an electric In carrying out the present invention, it is my purposeto provide an attachment of the class described, which will embody a setof deflecting blades arranged in advance of the fan. and connected tothe cage of the latter, and capable of'relative adjustment todifl'erentangular positions, so that the air from the fan may bedeflected, and means associated with the blades for holding the latterin adjusted position, thereby preventing accidental relative movement ofthe parts, .and these so arranged and correlatedblades after the latterhave been set.

It is also my purpose to provide an attachment of the class described,which may.

be quickly and conveniently attached to the cage of the fan, which maybe manufactured! and sold at a comparatively small cost, and

which will embody comparatively few as to reduce the possibility ofderangement to a minimum.

With the above and other objects in view, the invention". consists inthe construction, combination and arrangement of parts hereinafter setforth and falling within the scope of the claims.

In the accompanying drawings I Figure 1 is a view lnfront elevation ofmy attachment applied to an electric fan.

Fig. 2 is a top plan'view of the attachment removed from the fan.

Fig. 3 is a view in elevation of a detail of the attachment.

Fig. 4 is an enlarged side elevation of one of theblades.

Fig. 5 is a plan view of the plate, for holding the deflector blades andassociatedparts.

Referring now to the drawings in detail, 1 designates an electric fanincluding fan blades 2 mounted upon the armature shaft of the motor torotate withsaid shaft, and a circular cage 3 inclosing the fan blades.In

the present instance, my attachment includes a support composed of asingle length ofv Wire 4 bent upon itself between its ends to wardly, asat 9, and the upper ends of the portions 9 are formed to provide hooks10 that engage the ring ofthe cage to hold the wire against the outerface of the cage.

11 designates a plate having a straight edge 12 and an irregular edge13, and the irregular edge 13 is formed with notches 14 suitably spacedapart along such edge. This plate 11 is arranged horlzontally andthestraight edge is placed against the posts 5 and 7 and secured astridethe plate and projecting outwardly therefrom is a handle 15 formed of alength of wire bent. upon itself between its ends and having theextremities thereof outturned, as at 16, and arranged contiguous to thestraight edge 12 at the center of the latter.. These out-turned ends'16. embrace the posts 5 and act to hold the plate 11 hingedly to thewire support 4. The deflector blades are indicated at 17, and, in thepresent instance, are four in number, and each blade 17 is formed withan irregular cross slot 18 at the center thereof, and this slot 18 opensonto one edge of the deflector blade, as clearly illustrated in Fig. 4of the drawings. .The edge of the plate 17 contiguous to'the slot 18is'formed with outwardly extending wings 19 arranged at opposite sidesofthe slot 18, respectively.

In the use of the attachment, the support 4 to which the plate-'11 isconnected is secured to the cage of the fan, .as previously describedThe slots 18 of the blades 17 are now slipped over the plate 11 and thewings 19 on the blades bent around the posts 5 and i 7, respectively,thereby pivotally connecting the blades to the posts- Inthe applicationof the blades to the posts the plate 11 is raised slightly by the handle15, so that the to its original position, so'as to hold the blades 17against swin 'ng movement on the. pivotally connected to said supportand arposts.
